Air blown fiber systems use air to blow micro optical fiber cables through pre-installed microducts.
吹气纤维, 也被称为喷射纤维, is an efficient way to install fiber optic cable 和 facilitates future expansion of optical fiber networks. Fibers can be installed in areas that are hard to reach or that have limited access. Air Blown Fiber is also recommended for environments where there will be many changes 和 additions to the network. It also allows for duct installation before you know how much fiber is actually required, 和 so eliminates the need to install dark fibers. It also reduces splicing 和 interconnection points so optical loss is minimized 和 system performance is enhanced.
Air Blown Fiber (ABF) System Installation
ABF systems are made up of a network of microducts that connect at various locations. The components of the air blown fiber system include microducts, 吹风机, 光纤微电缆, 终止 橱柜，以及连接/终止硬件. 管道连接到吹风机. The blowing apparatus blows air through the ducts. This creates a vacuum inside the duct 和 pulls the microcable into 和 through the microduct. Duct distribution 橱柜 are installed everywhere the ducts branch to another location 和 at each end of every length of duct.

风吹纤维优点
空气吹入的纤维被吹入适当的位置, 而不是拉, puts no zero tensile stress on the fiber during installation 和 fiber splice points can be eliminated, lowering attenuation 和 increasing system performance 和 integrity.
Installing blown fibers ensures that the microduct can be reused for fiber expansion or replacement in the future by blowing out the existing microcables 和 blowing in new ones.
Air blown fiber systems offer cost savings 和 other benefits compared to traditional fiber systems. These benefits include reduced outside plant material, 更快的安装时间, fewer fiber connection points (which reduces the number of splices), 简化维修和保养, 和 a path for future evolving applications (such as adding new fibers).

选择合适的光纤
Selecting the right microduct is critical to the success of any microcable deployment. The formulation 和 surface finish of a microduct’s low-friction layers are vitally important to achieving long, 连续吹风距离. 同样地, 微电缆的最佳外径, 重量, stiffness 和 low friction jacket also play a critical role in installation performance. When the most appropriate microcable for an application is used with the right microduct, 这些关键特征结合在一起, 以一种协同的方式, 传递顺畅, 最大限度的吹气部署, 连续吹风距离.
